Digi and May posted on his thread under the alias
@fugnug. Like you said, May became convinced that one of the users was Tenleid talking shit about her, so she started making bitchy remarks on there and finally made a whole Youtube video "exposing" her.
People already suspected that fugnug was her, but she actually left KF screenshots in the video in which you could clearly see her logged in. After that Digi took over posting on that account, mostly trying to justify his trooning to the former fans there. Remember that at the time he tried to have May take over the name Digibro and narrate and edit his videos while he limited himself to writing the scripts as Digi-nee.
